Research to support: Blass (1991) reanalysed Milgram's participants to find that those who were more likely to disobey if they had internal locus of control.

Further research to support: Oliner and Oliner (1988) interviewed Germans who hid Jews during the war. They found that they had an internal locus of control and that they scored highly on social responsibility

Support for power of social support: Milgram's variations found that when two other confederates resisted authority, the rates of obedience dropped from 65% to 10%. This shows that the presence of a partner can influence disobedience.

Real life evidence to go against Locus of Control/social support: an order of a mass killing of Jews was given to the Reserve Battalion 101 but the option to do an alternative task was given. Several accepted the alternative task but the majority did not.
